Hello
Does anyone know how to calibrate the ABS module when you change the size of the tire and what of the DTC error?
That is, can the size of the tire be changed? Is it necessary to calibrate the ABS module?
My English level is not very good and I do not know all the possibilities that the UCDS software has. If anyone can inform me I would appreciate it.

Thank you very much

Tire size should be coded to PCM. If BCM and ABS module "shadow copies" differ from PCM you will get a DTC.

What would the procedure be then? What positions should I change so that I do not get error DTC?

Some tuners offer setting tire sizes/rotations. If you don't run a tuned pcm you can set this in bcm and initiate pcm learn procedure so it will adapt settings from bcm.

I really do not know how to perform this procedure. Anyway, thank you very much for the response. I will continue looking for how to do it without it being too complicated or that I am wrong and get broken in the car.

Best regards!!
